RTS always grabs 256Mb on startup
Two bugs really:
- on Windows, the RTS always reserves 256Mb of memory on startup.
- to use more than 256Mb, you have to use +RTS -M
I think this is a hangover from the days before HEAP_ALLOCED was implemented with an array lookup; I believe we could now implement MBlock on Windows without these drawbacks.
